按页面版块拆分mixins，再按需拼装
说明：这里只是举例，可以拆分；这样拆分并不合理；拆分非常适合用于UI组件开发；
1. 拆分为 page-search.js 、 page-content.js 、footer-pagination.js
- page-search.js
export default {
data() {
return {
// 查询配置
searchColumns: [{
key: 'keyword',
value: '',
label: '查询条件',
}],
// 查询条件
searchParams: {},
cloneParams: {},
}
},
created() {
let params = {}
this.searchColumns.forEach(item => {
params[item.key] = item.value;
});
this.searchParams = params;
this.cloneParams = JSON.parse(JSON.stringify(this.searchParams))
this.search()
},
methods: {
/**
* 查询
*/
search() {
this.pagination.page = 1;
this.getTableData();
},
/**
* 获取数据
*/
getTableData() {
this.table.loading = true;
this.$axios.get('/data/list.json').then(({ data }) => {
this.table.loading = false;
this.table.data = data.list;
this.pagination.total = data.totalCount;
}).catch(() => {
this.table.loading = false;
})
},
/**
* 重置
*/
reset() {
this.searchParams = JSON.parse(JSON.stringify(this.cloneParams))
},
/**
* 渲染查询条件
*/
genPageSearch() {
return (
<header class="page-search">
<es-row>
{this.genSearchItems()}
{this.genSearchBtns()}
</es-row>
</header>
)
},
/**
* 渲染 查询表单
*/
genSearchItems() {
return this.searchColumns.map(item => (
<es-col span={8} class="form-item">
<label>{item.label}</label>
{item.render ? item.render(this.$createElement, item) : this.genSearchItem(item)}
</es-col>
))
},
/**
*
* @param {Object} item 查询条件，单个配置对象
* @returns {vNode}
*/
genSearchItem(item) {
switch (item.type) {
case 'select':
return <es-select vModel={this.searchParams[item.key]} props={item.props}>
{item.props.options.map(opt => <es-option key={opt.value} label={opt.label} value={opt.value} />)}
</es-select>
default:
return <es-input vModel={this.searchParams[item.key]} props={item.props} />
}
},
/**
* 渲染 查询按钮
*/
genSearchBtns() {
return (
<es-col span={8} class="form-item">
<es-button type="primary" loading={this.table.loading} vOn:click={() => this.search()}>查询</es-button>
<es-button vOn:click={() => this.reset()}>重置</es-button>
</es-col>
)
},
}
}
- page-content.js
export default {
data() {
return {
// 表格
table: {
loading: false,
data: []
},
// 表格配置
tableColumns: [{
label: '姓名',
key: 'name',
props: {
width: 140
},
render: (h, { row }) => {
return <span>{row.name}</span>
}
}],
}
},
methods: {
/**
* 编辑
* @param {Object} row 操作的行数据
*/
editItem(row) {
console.log(row)
},
/**
* 删除
* @param {Object} row 操作的行数据
*/
deleteItem(row) {
console.log(row)
},
/**
* 渲染 主内容区域
*/
genPageContent() {
return (
<main class="page-content">
{this.genTable()}
</main>
)
},
/**
* 渲染 table区域
*/
genTable() {
return (
<es-table data={this.table.data}>
{
this.tableColumns.map(item => {
if (item.render) {
return <es-table-column label={item.label} props={item.props} scopedSlots={{
default: (props) => item.render(this.$createElement, props)
}} />
} else {
return <es-table-column prop={item.key} label={item.label} props={item.props} />
}
})
}
</es-table>
)
},
}
}
- footer-pagination.js
export default {
data() {
return {
// 分页
pagination: {
page: 1,
size: 20,
total: 78
}
}
},
methods: {
/**
* 改变分页页数
* @param {Number} page 页数
*/
changePage(page) {
this.pagination.page = page
this.getTableData()
},
/**
* 改变每页条数
* @param {Number} size 每页条数
*/
changeSize(size) {
this.pagination.size = size
this.changePage(1)
},
/**
* 渲染 底部分页
*/
genFooterPagination() {
return (
<footer class="page-pagination">
<es-pagination
vOn:size-change={this.changeSize}
vOn:current-change={this.changePage}
current-page={this.pagination.page}
page-sizes={[10, 20, 50, 100]}
page-size={this.pagination.size}
layout="total, sizes, prev, pager, next, jumper"
total={this.pagination.total}
/>
</footer>
)
},
}
}
2. 组装mixins
- page-mixins.js
import pageSearch from './page-search'
import pageContent from './page-content'
import footerPagination from './footer-pagination'
export default {
mixins: [
pageSearch,
pageContent,
footerPagination
],
render() {
return (
<div class="page-container">
{/* 查询条件 */}
{this.genPageSearch()}
{/* 内容区域 */}
{this.genPageContent()}
{/* 底部分页 */}
{this.genFooterPagination()}
</div>
)
}
}
3. 引用mixins（嵌套引用）
<script>
import pageMixins from '@/mixins/page-mixins.js'
export default {
mixins: [pageMixins],
data() {
return {
// 接口配置
apis: {
search: '/data/list.json',
delete: '/api/delete'
},
// 自定义 查询条件展示
searchColumns: [
{
label: '姓名',
key: 'name',
value: '',
},
{
label: '状态',
key: 'status',
value: true,
type: 'select',
props: {
options: [
{ label: '开启', value: true },
{ label: '关闭', value: false },
],
},
}
],
// 自定义 table配置展示
tableColumns: [
{
label: '姓名',
key: 'name',
},
{
label: '状态',
key: 'status'
},
{
label: '操作',
props: {
width: 140
},
render: (h, { row }) => {
return (
<div>
<es-button size="mini" type="primary" plain vOn:click={() => this.editItem(row)}>编辑</es-button>
<es-button size="mini" vOn:click={() => this.checkDetail(row)}>详情</es-button>
</div>
)
}
}
],
}
},
methods: {
/**
* 查看详情
* @param {Object} row 操作的行数据
*/
checkDetail(row) {
console.log(row)
}
},
render() {
return (
<div class="page-container">
{/* 查询条件 */}
{this.genPageSearch()}
{/* 自定义 内容区域 展示*/}
<main class="page-content">
<div style="padding: 8px 0 0 8px"><es-button size="mini">更新全部状态</es-button></div>
{this.genTable()}
</main>
{/* 底部分页 */}
{this.genFooterPagination()}
</div>
)
},
}
</script>
